[Q] Galaxy S4 Clone screen not working

Hello,
I've recently bought Galaxy S4 clone and it was working great, till I tried rooting it.
The rooting was through *android kingo root* and everything went flawless. After 15 minutes, I noticed that the screen is black but there's backlight led. I thought it might be out of charge or any silly reason, tried every possible solution but couldn't get any help.
The phone turns on and I can receive calls and reply by guessing the place, I also can hear the unlock/lock sounds. But no luck in turning screen on.
Any help guys ?

this is urgent
Bump.
Sorry but the case is realy urgent. Please enlighten me with any help. /:

This is really important guys /:
Hope anyone can give me a hint ..

Clone
Don't know about a clone but i can think of just two things,
First maybe it's a hardware problem and need to be repaired!
Second if it is caused due to rooting or anything then you can try flashing the official firmware of your device (if available).

Well I think its a hardware problem, because the phone starts up and I can hear sounds.
I could get a screenshot from the phone and see the karnel/baseband ... etc (Attachments)
I don't know where I could find a replacement screen or a rom flashed. Could you assist me with some hints or links?
Thanks.

A screen you should be able to order from china. A rom, now that will be harder to find as clone have almost no support or developers.

I believe its a hardware one's. The touch works fine
Could you give me a link? I couldn't find any screen.

Well see thats the issue with clones. No telling what part they used from where.
This is all I could find.

To be honest it maybe cheaper to replace the device with an authentic version from somewhere like swappa or something.

Well, at the moment I have no money at all. I spent it all on the phone and didn't complete 2 weeks. I will try to save some money in the next months to buy another phone or parts.
If anyone has another solution please tell me.

Is there a way to solve the yellow line?

I everyone, sorry if I ask.
I've bought a chinese OPO and I've seen that, at the bottom of the screen I've the "famous" yellow line.
Is there a way to fix it?
Thanks in advance.

Yes, I'm under warranty but I've bought the phone from China and I'm from Italy, only the ship cost will be more than the repair.
There's no place to repair a china phone here, nobody even known the phone
But it's a problem that has a lot of OPO and the manufacturer said that, they're good enough and, even N% has yellow screens...
But I'm really not happy with this phone, not only for the yellow line.

There is no way to fix it, with usage and time it gets slightly better. 99% of phones have this, so you should not have bought the phone, if you think this is a deal breaker.

I didn't know that this kind of phone has this kind of screen. Obviously I never bought a phone with this defect.
I really never bought a phone even if I had known the state of Cyano 11s.
But it'd definitely my fault.
Thanks for the answers.

There's an entire thread dedicated to this. Try using a UV lamp (found at a nail salon) for ten minutes with the device turned off.

[Q] Touch+display dead

The display stopped working 2-3 days ago. On booting i can see the google logo for 2-3 seconds before the screen goes dark. The phone works and i can hear dings of messages, but i cant access any of it. Once i kept shut it for a day i was able to see the screen for 10-15 seconds( i used this window to remove the screen lock so that i can use the usb transfer ). Now keeping the phone shut for long duration has no effect.
I can see the fastboot screen but not the recovery screen throught it.
I also bought a slimport so that i could see the screen on my pc. It works (not for the fastboot or recovery), however the touch doesn't work and the volume and power buttons response is too sluggish. I can connect the mouse but it is of no use as i can't see the screen on PC and use the mouse at the same time. I tried adb ( i have no experience of it ) but i cant touch the allow pernmissions key on the screen for the above reasons. Also what advantage would adb be in this case?.
Any advice ?
PS: i have cyanogenmod

I think ram is your only option. It definitely sounds like it's hardware and not software related.

Sorry, i don't follow. U mean a ram replacement is needed ?

It was a typo.. He meant RMA
- Sent from an IceCold Hammerhead!

Oh, you mean sending it to LG for servicing? I am a bit hesitant since i have cyanogenmod and also am in india and i doubt they will give a replacement. I think going back to stock rom and then sending it for repairs might help but i have no idea how to go about doing that in this situation.

Its all done via fastboot or lg flash tool. Probably the latter is best for you. Have a read of the guides in my signature

How can i do it using fastboot ?

I do t understand the question. Is this question one you're asking having already read the fastboot return to stock guide?

Same issue I had pretty much, it died about 2 months ago. I was still able to copy all of my files, phone worked perfectly but the screen was black. Had it replaced it no time. Is that by any mean a 311k? I've seen another thread like that pop up lately.

I don't know yet, I'm just trying to figure out whether it's a particular batch that started failing or it's completely random, just curious. The two replacements I was sent were 403K. Build is perfect, but they both had some light bleed issues. Looks like every batch comes with some good and some bad, QC definitely hasn't been too great on this phone.

They're not really built in batches. Manufacturing was continuous. They just changed the serial number every time the month changes so I dont think this would actually mean anything

I know but I'd still use it as a milestone more than anything, I mean there have been some differences in the units (eg bigger speaker holes), this way it's easier to track them along the timeline, because they definitely do change something in the manufacturing process from time to time if they have to make up for issues or something. They also did it with the N4 if I remember well.

Speaker holes is a bad example because even the latest built devices it was still a lottery whether you got bigger or smaller holes. That's down to what you mentioned earlier, QC

I was able to unroot and flash the stock image. The problem still exists though, so it has to be a hardware issue. Fortunately the phone is still in warranty.
Thanks for all the support.

Well, then you have these options
- Fix it yourself (Oh boy)
- Pay for an repair service ( On hard bricked devices the mainboard is broken)
I would say fixing it yourself costs arround 75€. Let someone else fix it maybe 100€, so think about it... Im sorry for you. I bricked my phone last week too.

Btw you remember when i said i was working on Lineage? I can tell you one thing: I booted to android 6! Well, i used others work, but hey! (For everyone reading it, no i am not going to relase it in the near future.)
